Seeking a suggestion on Iterator, Looping, JSON Aggregator

Hi I’m quite new with Make but really enjoy all the features and capability.

I’m building this automation from a WebHooks listening to a Softr form with file upload capability. I got it to work so far when i only upload one single file. If I choose multiple files to upload, it always picks the first file.

I know I need to add an iterator of some sort in between but what’s the easier way to loop through this and count the number of uploading files to be processed and pick the string part of the filename in the URL address.

Any suggestions?

Many thanks in advance.
